It is believed by the scientists that there is a super massive black hole at the center of the galaxy which is created due to collision of many black holes and it is million times larger than our sun. It is very bright because of the large light attracted towards it. We can say that the mysterious bright object is a black hole which seems to be bright but all the lights is from another source.
quasar
A mysterious bright star-like object in the core of a galaxy could be a supermassive black hole surrounded by an accretion disk of gas and dust, emitting intense radiation as material spirals inwards. It might also be a quasar, which is an extremely luminous active galactic nucleus powered by a black hole consuming surrounding matter. Alternatively, it could be a rare type of star or a stellar explosion, such as a supernova, that temporarily outshines its surroundings. Observations and studies in various wavelengths of light can help determine the object's true nature.
